in numbers of pounds with the acreage, 574,884 

 on 574,884 acres. 



"In Scotland, Turnip Fly was present in 

 various localities, or was generally prevalent to a 

 serious extent in eleven counties. The acreage 

 under turnips and swedes in these eleven 

 counties, as stated in the Government returns 

 quoted above, was 194,105 acres. Half of this 

 total of 194,105 acres is 97,052, and following the 

 previous method of calculation, the loss on this 

 would be for seed, 10,918 75. ; for one re-sow- 

 ing at 155. per acre, 72,789 ; for one re-sowing at 

 i per acre, 97,052. The loss, therefore, on the 

 amount of acreage named in twenty-two English 

 and eleven Scottish counties would at the above 

 estimate stand thus : For seed alone, 75,592 i6s. ; 

 for one re-sowing, including, seed and cultiva- 

 tion at the rate of 155. per acre, 503,952; the 

 same at the rate of i per acre, 671,936. This 

 amounts to just a little more (or considerably 

 more) than half a million, if the larger rate of i 

 per acre is taken ; but though the direct amount 

 of money loss on unreturned outlay for seed and 

 re-sowings in the districts known to have been 

 attacked amounts to this enormous sum, and can 

 at least be fairly well estimated, beyond this 

 there is still a heavy loss to be considered on 

 lesser value of the white turnip than the swede 

 crop, and also on the deficiency of the late- 

 sown crops, as well as in some cases the total 

 loss. Also the deficiency of crops affects other 

 points of agricultural supply, as want of cattle- 

 food, and consequent lesser supply of manure, 

 depreciation of price of stock, etc. ; so that
